[Qemu-devel] [PATCH] few compile time warnings removed

[Stefano Stabellini <stefano.stabellini@eu.citrix.com>]

Few small changes to remove some compile time warnings:

- we are not initializing the qemu_alarm_timer pointer in
init_timer_alarm, so I am adding a NULL initialization;

- in the headers include code, we are doing something like:

#ifdef
/* BSD stuff */
#else
#ifndef __sun__
/* linux stuff */
#else
/* sun stuff */
#endif
#endif

that works most of the times but it fails when you try to compile qemu
on mini-os, that is posix but it doesn't define either __sun__ or 
__linux__, so I am changing it to:

#ifdef
/* BSD stuff */
#else
#ifdef __linux__
/* linux stuff */
#endif
#ifdef __sun__
/* sun stuff */
#endif
#endif
